Pacific West Botanicals From Planting instructions: under Pests and Diseases Pillbugs Pillbugs and Sowbugs have sectioned shells and seven pairs of legs. Pillbugs roll up into black balls about the size of a pea. Sowbugs are gray and cannot roll up tightly. Their principal food is decaying vegetation. They also eat young seedlings and melon skins. They live in thick mulch so keep compost far from plants and dry soil surface between waterings. |
